Description:

RELATED APPLICATION

[0001] This application is a continuation-in-part of U.S. application Ser.
No. 13/296,883 filed Nov. 15, 2011, which is hereby fully incorporated
herein by reference.

[0003] In critical care environments, a single patient can be connected to
multiple infusion pumps or other tubing-based delivery or removal systems
at the same time. Because of this, a multitude of medical tubing can be
near and around the patient, making it difficult for medical
professionals to know which tubing relates to which infusion pump,
delivery system, or removal system. Further, parameters such as route of
infusion, drug interaction, and whether the line is putting fluid into
the patient's body or carrying fluid away from the patient's body, for
example, are critical to the care of a patient. If the wrong medication
is placed in the wrong set of tubing, the results can be fatal. Thus, the
organization and identification of tubing lines is vitally important.

[0004] Currently, the identification of tubing lines is done by hand,
often by a medical professional hand-tracing the tubing from a delivery
or removal device, through the span of tubing, and to the patient, or
vice-versa. With respect to infusion systems, the medical industry has
devised standardized colors and patterns to indicate characteristics of
medical tubing, like route of infusion and type of tube. Thus, more
updated methods of identifying tubing involve hand-labeling a tubing line
with these standardized markings by adhering a label to the line after
initial implementation or the tracing described above. In some instances,
a single line of tubing can have multiple labels affixed to it. However,
the human-executed practices described above are not only time-consuming,
but also prone to mistakes in labeling or identification due to human
error and a lack of robustness in or reliability of adhesive labels and
other rudimentary visual identification schemes.

[0005] Additionally, even when the multitude of lines are labeled
correctly, there remains a difficulty in reading and evaluating the
labels when the room in which the patient resides is not well lighted.
For example, when a medical professional enters a patient's darkened
room, such as when the patient is sleeping at night, in order to check
the connectivity or status of one or more of the lines, the professional
will often have to turn the overhead room lights on, or have a
supplementary light to position on the lines and labels, like a
flashlight. The turning on of room lights or use of a flashlight around
the patient may be disruptive to the patient's sleep. Additionally, the
use of a flashlight can be cumbersome, especially when both of the
professional's hands are needed for patient care. Further, some drugs are
sensitive to the wavelength of certain light, thereby limiting the types
of lights that may be used around medical lines.

[0006] In addition, existing medical tubing provides no indication of the
operating status or, in cases of problems with the tubing or infusion,
alerts for the attending medical professional. In order to check the
operating status of the infusion device and attached tubing, the medical
professional must first inspect the device, inspect the interface to the
tubing, and subsequently trace along the tubing to evaluate a proper
flow. Similarly, medical professionals are often not alerted when there
is a problem with the tubing or infusion; the entire length of tubing
must be visually inspected for blockages or occlusions. Thus, in addition
to the problem of identifying existing medical tubing, a problem exists
in identifying operating and problem statuses.

[0007] Further, medical tubing detection and management has heretofore
been problematic for medical practitioners. In hospitals, for example,
there may be a large number of tubes, cords, and cables present in
patient care areas--particularly in those areas or rooms where patients
are receiving intensive care. A relatively easy and efficient way of
identifying and organizing medical and infusion tubing is therefore
desirable, along with identification of corresponding tubing sets and
drug infusion routes. Such information could be vitally important in,
e.g., determining acceptable compatibilities and desired interactions of
drugs being administered to a patient.

[0008] Therefore, there is a need for an automated, safe, and effective
way of identifying medical tubing, as well as for identifying any
operating statuses or problem statuses with the flow of the medical
liquid within the tubing. There is also therefore a need for systems for,
and methods of, medical tubing detection and management.

SUMMARY

[0009] Embodiments relate to illuminated medical tubing, such that
individual medical lines are identifiable based on an illumination or
color scheme. This disclosure also describes novel and inventive systems
for, and methods of, medical tubing detection and management.

[0010] In an embodiment, a medical tubing set comprises a fluid conduit
adapted to convey a medical fluid, an optical element coupled to the
fluid conduit and configured to provide illumination, and a power source
configured to power the optical element.

[0011] In an embodiment, a method of operating a medical tubing set
comprises installing the medical tubing set in a medical device at a
first end and in a patient at a second end, setting at least one
operating parameter of the medical tubing set, sensing at least one
characteristic of the medical tubing set, comparing the at least one
sensed characteristic against the at least one operating parameter, and
illuminating the medical tubing set based on at least the comparison of
the at least one sensed characteristic and the at least one operating
parameter.

[0012] In an embodiment of a method of operating a medical tubing set, the
medical tubing set comprising a fluid conduit adapted to convey a medical
fluid, an optical element coupled to the fluid conduit and configured to
provide illumination, and a power source configured to power the optical
element, the method comprises installing the medical tubing set in a
medical device at a first end and in a patient at a second end; providing
a source of power with the power source; applying the source of power to
the optical element; and illuminating the fluid conduit with the optical
element.

[0013] The subject matter hereof thereby improves the way medical tubing
is identified in a critical care environment. Because the tubing provides
a visual indication, no hand-tracing of tubing from, e.g., the infusion
device, through the span of tubing, and into the patient is required.
Additionally, labels adhered to the tubing, or other rudimentary visual
identification schemes, are no longer needed to identify characteristics
of the tube, like route of infusion and type of tube; these
characteristics can be indicated by the illumination component. Likewise,
because the tubing is illuminated, the tubing is identifiable even in a
darkened room, and thus no supplementary light is needed to identify
individual tubes or labels. Further, sensors integrated into the tubing,
like pressure sensors, occlusion sensors, fluid flow sensors, temperature
sensors, liquid density sensors, air bubble sensors, salinity sensors, pH
sensors, dissolved oxygen sensors, conductivity sensors, and electrolyte
sensors, for example, provide data about the tubing and fluid that can be
accumulated and subsequently reported as a visual indication by the
illumination component. In this way, emergency situations can be
instantaneously expressed by a visual indication. Manufacturing
advantages also exist in embodiments. Existing medical tubing
manufacturing can be modestly altered or supplemented in order to produce
the tubing of the subject matter hereof. Similarly, in embodiments,
existing medical devices and medical tubing can be retrofit such that the
subject matter hereof is usable on devices and tubing not originally
designed for it. In another advantage, various components of embodiments
are highly reusable, thus lowering the cost to practitioners.

[0014] The most common source of occlusions is a clamp on the medical
tubing that is previously applied to the tubing but subsequently
forgotten by hospital staff. Consequently, in another advantage, when a
clamp is placed on embodiments, the clamp also acts as a stimulus for the
passing illumination by blocking, altering, restricting, or otherwise
changing the optical path. As a result, in embodiments, the passing
illumination is mostly terminated, and thereby highlighted, at the
forgotten clamp. Embodiments can thus provide a readily discernable
visual indication of forgotten clamps.

DETAILED DESCRIPTION

[0045] Embodiments relate to an illuminated medical tubing set that
provides visual indications of characteristics relating to the type and
operating status of the tubing. In embodiments, single and dual lumen
tubing can be used. In one dual lumen embodiment, one lumen is used is
used as the lighted channel, and the other lumen is used to transport the
drug or fluid. In another embodiment, an inner lumen is nested within an
outer lumen, whereby either the inner lumen is used as the lighted
channel and the outer lumen is used as the fluid conduit, or the outer
lumen is used as the lighted channel and the inner lumen is used as the
fluid conduit. The inside surface of a single channel of tubing is
optically coated with a side-emitting material in another embodiment. In
such an embodiment, a single channel is utilized as the conduit for both
the transportation of the fluid and the transportation of the light or
color. In another embodiment, the outside surface of a single channel of
tubing is optically coated with a side-emitting material. Both the
outside and inside surfaces of a single channel of tubing are optically
coated with a side-emitting material in another embodiment. In yet
another embodiment, a segment of electro-luminescent (EL) wire is coupled
to medical tubing such that, when current is passed through the EL wire,
the wire and consequently, the adjoining tubing, are illuminated.
Light-emitting diodes (LEDs) are positioned at opposite ends of or along
the tubing in order to illuminate the length of tubing in another
embodiment. Various other combinations and configurations of these and
other components can be implemented in other embodiments.

[0046] Embodiments also relate to systems for, and methods of, medical
tubing detection and management, that may provide relatively easy and
efficient ways of identifying and organizing medical and infusion tubing,
identifying corresponding tubing sets and drug infusion routes, and
determining acceptable compatibilities and desired interactions of drugs
being administered to a patient.

[0047] Referring generally to FIGS. 1A-1C, block diagrams of an
illuminated tubing set system 100 are depicted, according to embodiments.
Embodiments of illuminated tubing set system 100 generally comprise an
optical element 102, a fluid conduit 104, and a power source 110. Example
embodiments of illuminated tubing set 100 are described below. In
general, power source 110 interfaces with optical element 102, and
optical element 102 is configured to illuminate tubing set 100.
Optionally, and as depicted in FIG. 2, in another embodiment, illuminated
tubing set 150 can further comprise a pressure sensor 106 and a
microcontroller 108. Additional sensors, such as to monitor other
characteristics of the tubing, fluid, or surrounding environment, can
also be included in other embodiments. For example, an occlusion sensor,
temperature sensor, flow sensor, liquid density sensor, air bubble
sensor, salinity sensor, pH sensor, dissolved oxygen sensor, conductivity
sensor, electrolyte sensor, or any combination thereof, can be included
in embodiments.

[0048] In another embodiment (not depicted), illuminated tubing set 150
can comprise optical element 102, fluid conduit 104, power source 110,
and one or more sensors, without microcontroller 108. Further, one or
more sensors can comprise, for example, a pressure sensor, occlusion
sensor, temperature sensor, flow sensor, liquid density sensor, air
bubble sensor, salinity sensor, pH sensor, dissolved oxygen sensor,
conductivity sensor, electrolyte sensor, or any combination thereof. In
embodiments without microcontroller 108, an integrated circuit (IC) or
other generic chip can optionally be included. The IC is configured to
provide information to device interface 112 via an electronic signal. In
an embodiment, the IC can provide identifying information such as part
number, lot number, or expiration date, for example.

[0049] Referring again to FIG. 1A, optical element 102 provides an
illuminated visual indicator for tubing set 100. In embodiments, optical
element 102 runs continuously and lengthwise for the length of tubing set
100, as depicted, for example, in FIG. 1c. The visual indicator in
embodiments could therefore be substantially as bright and illuminated at
the midpoint of tubing set 100 as it is at the interface to power source
110. For example, in an embodiment, optical element 102 comprises a
side-emitting optical coating running the length of tubing set 100 and a
light-generating element, such as a laser or other concentrated light
source. In such an embodiment, power source 110 powers the
light-generating element, which directs light along the side-emitting
optical coating. Light is reflected along the length of tubing set 100 to
illuminate tubing set 100. The optical coating can comprise an adhesive
acrylate-based cladding solution, or any other coating appropriate for a
plastic or silicone substrate. In an embodiment, the optical path for
optical element 102 is co-extruded with fluid conduit 104 at the time of
manufacture. In another embodiment, optical element 102 comprises an
illuminated EL wire running the length of tubing set 100. In another
embodiment, optical element 102 is positioned at discrete points along
tubing set 100, for example, and comprises one or more illuminable LEDs,
such as multi-color LEDs. In such an embodiment, power source 110 powers
discrete lights or indicator elements at certain illumination points, for
example, at the interface point with power source 110, as depicted, for
example, in FIG. 1B. Both a greater number and lesser number of
illumination points are considered. For example, optical element 102
points can be at the interface with power source 110 and near the patient
contact site. In another example, illumination points can be at the
interface point with power source 110, at the midpoint of tubing set 100,
and near the infusion or patient contact site.

[0050] Optical element 102 can be configured to provide white light or
colored light, or to provide no light, or to selectively alternate
between one or more lighted and/or non-lighted settings. Further, optical
element 102 can provide varying degrees of brightness. In certain
situations, like when a patient's room is darkened--at night, for
example--the brightness of optical element 102 can be reduced. The
reduced intensity light of optical element 102 is still easily visible in
the darkened ambient lighting, yet not bright enough to disturb the
patient. Conversely, when the ambient lighting is brightened--during the
day, for example--the brightness of optical element 102 can be increased
to increase the ease of visibility of tubing set 100. Additionally,
optical element 102 can be configured to provide flashing or patterned
light. Examples of such flashing or patterned light are given below.
Additional optical elements, like a chemiluminescent fluid, can also be
included in other embodiments.

[0051] Fluid conduit 104 is used to transmit fluid in a critical care
environment. For example, fluid conduit 104 can transmit medication from
an infusion pump to a patient. Alternatively, fluid conduit 104 can
provide the conveyance for removing fluid from a patient. Fluid conduit
104 generally comprises a cylinder with a diameter wide enough for fluid
to flow appropriately for the medical application. Thus, fluid conduit
104 can have diameters of different sizes in various embodiments. For
example, fluid conduit 104 having diameters of about 0.015 inches to
about 3.0 inches are contemplated. Other diameters are also considered.
Fluid conduit 104 is typically made of a flexible silicon plastic
appropriate for a medical environment, such that it is odorless,
tasteless, and inert. Further, fluid conduit 104 is nonreactive to body
tissues and fluids and can withstand repeated sterilizations. Other
appropriate materials are also considered, like polyvinyl chloride or any
other appropriate thermoplastic polymer. Fluid conduit 104 can also be of
varying lengths, depending on the medical application. In embodiments,
fluid conduit 104 can provide the conveyance for both the medical fluid
as well as the housing for optical element 102. Typically, fluid conduit
104 is clear or transparent so that the fluid flowing throughout fluid
conduit 104 is visible through the walls of the cylinder. In other
embodiments, however, fluid conduit 104 can be partially or fully
translucent or opaque.

[0052] Power source 110 provides a source of the power for optical element
102. In embodiments, power source 110 can be integrated into the medical
device to which tubing set 100 interfaces. In other embodiments, power
source 110 can be integrated within the body of fluid conduit 104 or
another portion of tubing set 100 itself. Power source 110 generates or
conveys the power required of the particular embodiment of optical
element 102. For example, power source 110 can be a battery. In another
example, power source 110 is an electrical connection to the power source
of the medical device.

[0053] In an embodiment, for example one in which optical element 102
comprises a light-generating element and a side-emitting optical coating
from which light can reflect, power source 110 is a battery that powers
the light-generating element. A beam of focused light is directed by the
light-generating element appropriately along the sides of the conduit of
the optical coating to illuminate tubing set 100. In another embodiment,
power source 110 comprises a source of alternating current, where optical
element 102 comprises, for example, a length of EL wire. The alternating
current is applied to the EL wire to illuminate the wire, the conduit
housing optical element 102 and thus, tubing set 100. In another
embodiment, power source 110 includes a voltage source designed to power
an LED, where optical element 102 comprises an LED. The above-described
power sources are provided for example only and are not intended to be
limiting for power source 110. Any appropriate power source can be used.
For example, in embodiments, direct current, battery, photovoltaic,
linear regulated, switched mode power sources, or any other useful power
source can be utilized.

[0054] In embodiments, and referring to FIG. 2, tubing set 150 can further
comprise pressure sensor 106. Pressure sensor 106 is used to monitor the
pressure of the fluid within fluid conduit 104. By measuring the
pressure, emergency or alertable situations can be detected for the fluid
flow within fluid conduit 104. In embodiments (not depicted), a tubing
set can comprise any useful sensor, for example, occlusion sensor,
temperature sensor, flow sensor, liquid density sensor, air bubble
sensor, salinity sensor, pH sensor, dissolved oxygen sensor, conductivity
sensor, electrolyte sensor, or any combination thereof. Similar to the
above-described monitoring of pressure sensor 106, any of the
aforementioned sensors can monitor fluid conduit 104 and subsequently
relay emergency or alertable situations, depending on the specifics of
the respective sensor.

[0055] In embodiments, tubing set 150 can further comprise microcontroller
108. Microcontroller 108 is used to capture the pressure sensed by
pressure sensor 106. Algorithms regarding pressure changes can be
programmed into microcontroller 108. In an example, if the measured
pressure is outside of a particular boundary or the measured delta is
outside limits placed on a previously-measured acceptable value, an alert
situation may be present. Further, microcontroller 108 provides an
interface to control power source 110. In this way, various colored
lights or flashing patterns can be implemented. In the alert situation
described above, microcontroller 108 can signal to power source 110 that
a non-standard operating status should be indicated. Myriad algorithms
can be implemented, given this framework, to alert and provide status of
the operation of the tubing set. Examples are given herein below.

[0056] Device interface 112 can provide an interface for programming basic
operation, alarm indicators (including appropriate limits), colors, and
other operating parameters into microcontroller 108. In an embodiment,
device interface 112 is implemented as part of a medical device, such as
an infusion pump. In another embodiment, device interface 112 is
implemented as a stand-alone component of tubing set 150.

[0057] Device interface 112 can be configured to provide standardized
operating parameters to microcontroller 108. Standardized profiles or
configurations having standardized operation, alarm indications, colors,
and other operating parameters can be implemented for each medical device
for a particular hospital site. Each type of medical device can have a
specific profile with operating parameters unique to that device.
Similarly, a specific profile can be developed for each set of tubing
implemented having a specific sensor or set of sensors. Device interface
112 can be configured to install these profiles, and thereby adjust the
operating settings, prior to the use of the medical device. For example,
a particular hospital could standardize all occlusion pressure alarms to
flash tubing set 150 with the color red. Such a configuration allows for
uniformity across an entire hospital site, thus further easing burden on
medical professionals and further providing value with tubing set 150
use. At that particular hospital site, all medical professionals would
know that a flashing red tubing set indicates an occlusion problem.

[0058] Referring to FIG. 3, an embodiment of a dual lumen tubing set 300
is depicted. Dual lumen tubing set 300 generally comprises an optical
interface 302 and a fluid conduit 304. Optical interface 302 can be, for
example as described above with respect to optical interface 102, a fiber
optic channel, a length of EL wire extending throughout the channel, or a
series of LEDs placed along the channel, among others. Optical interface
302 and fluid conduit 304 are immediately adjacent each other in one
embodiment so that when optical interface 302 is illuminated, fluid
conduit 304 is also illuminated.

[0059] Referring to FIG. 4, an embodiment of a dual lumen tubing set 400
is depicted. Dual lumen tubing set 400 generally comprises an inner lumen
402 and an outer lumen 404. Inner lumen 402 is nested within outer lumen
404 such that inner lumen 402 is completely enclosed by outer lumen 404.
In an embodiment, inner lumen 402 provides the fluid conduit and outer
lumen 404 provides the housing for the optical interface for dual lumen
tubing set 400. When illuminated using appropriately clear or transparent
lumens, the optical element in outer lumen 404 illuminates inner lumen
402 and the fluid flowing throughout. In another embodiment, inner lumen
402 provides the housing for the optical interface and outer lumen 404
provides the fluid conduit for dual lumen tubing set 400. When
illuminated, the optical element in inner lumen 402 illuminates outer
lumen 404 and the fluid flowing throughout. In embodiments, the optical
interface can be, as described above with respect to optical interface
102, a fiber optic channel, a length of EL wire extending throughout the
channel, or a series of LEDs placed along the channel. In other nested
embodiments (not depicted), additional lumens can extend throughout the
outermost lumen, with multiple fluids flowing throughout, depending on
the medical application. Whichever lumen is chosen as the fluid conduit
can illuminate the remaining fluid conduit lumens.

[0060] Referring to FIG. 5, an embodiment of tubing set 500 using an EL
wire is depicted. Tubing set 500 generally comprises an optical element
502 and a fluid conduit 504. In such an embodiment, optical element 502
is a length of EL wire. Optical element 502 is encircled around and
coupled to the outer wall of fluid conduit 504 in a crisscrossing
pattern. Similarly, referring to FIG. 6, another embodiment of a tubing
set 600 using EL wire is depicted. Tubing set 600 generally comprises an
optical element 602 and a fluid conduit 604. Again, in such an
embodiment, optical element 602 is a length of EL wire. Optical element
602 is coupled to the outer wall of fluid conduit 604 along one side of
the outer wall. When optical element 502 or optical element 602 are
illuminated, respective fluid conduits 504 or 604 are similarly
illuminated. In operation, to illuminate optical element 502 or 602 and
thus fluid conduit 504 or 604, an alternating current is applied to one
end of the EL wire of optical element 502 or 602.

[0061] Referring to FIG. 7, an embodiment of tubing set 700 comprising a
side-emitting optical coating is depicted. Tubing set 700 generally
comprises an optical element 702 and a fluid conduit 704. In such an
embodiment, optical element 702 comprises a side-emitting optical coating
and a light-generating element. The side-emitting coating of optical
element 702 is coated along the inside walls of fluid conduit 704. The
combination of the light-generating element and the optical coating, when
light is directed by the light-generating element along the coated walls
of fluid conduit 704 provides an illuminated fluid conduit 704. Tubing
set 700 therefore has a single conduit; fluid conduit 704 provides the
conveyance for both the medical fluid as well as the housing for the
optical element.

[0062] Similarly, referring to FIG. 8A, an embodiment of tubing set 800
also comprising an optical coating is depicted. Tubing set 800 generally
comprises an optical element 802 and a fluid conduit 804. Similar to
tubing set 700, optical element 802 comprises a side-emitting optical
coating and a light-generating element. However, unlike tubing set 700,
tubing set 800 has the optical coating along the outer wall of fluid
conduit 804.

[0063] In operation, to illuminate fluid conduit 704 or 804, a beam of
focused light is directed appropriately at one end of fluid conduit 704
or 804 by the light-generating element of optical element 702 or 802,
respectively, so that the light reflects along the coated sides of fluid
conduit 704 or 804, respectively.

[0064] Referring to FIG. 8B, an embodiment of tubing set 850 also
comprising an optical coating is depicted. Tubing set 850 is a
combination of tubing set 700 and tubing set 800. Tubing set 850
generally comprises an inside optical element 702 and an outside optical
element 802, both optical elements 702 and 802 comprising a coating of
side-emitting material such that there is optical coating on both the
interior and exterior of the tubing wall, and a fluid conduit 854. In
tubing set 850, the tube wall itself comprises the optical path.

[0065] In operation, to illuminate fluid conduit 854, a beam of focused
light is directed appropriately within the wall of fluid conduit 854 by
the light-generating element of optical element 702 or 802, respectively,
so that the light reflects within the coated sides of fluid conduit 854.
The combination of the light-generating element and the two optical
coatings, when light is directed by the light-generating element within
the wall of fluid conduit 854 provides an illuminated fluid conduit 854.

[0066] Referring to FIG. 9, an embodiment of tubing set 900 having one or
more LEDs is depicted. Tubing set 900 generally comprises an optical
element 902 and a fluid conduit 904. In such an embodiment, optical
element 902 comprises at least one LED. As depicted, optical element 902
is positioned near an opening of fluid conduit 904, though other
positionings, configurations, and arrangements are possible in other
embodiments. As appropriate, additional optical elements 902 can be
positioned along fluid conduit 904 to provide consistent illumination of
fluid conduit 904 when optical elements 902 are illuminated. In
operation, to illuminate optical element 902, a voltage is applied to the
LED to thereby illuminate the LED and fluid conduit 904.

[0067] In operation generally, referring to FIG. 10, a tubing set is
installed at 1002. Depending on the embodiment and application,
installation can be any variation of securely coupling one end of the
tubing set to a medical device and the opposite end to a patient, or as a
drain from a patient to a waste-capturing device. Fluid conduit 104 is
appropriately coupled to the fluid source. Further, optical element 102
and power source 110 are appropriately coupled together if required. For
example, one installation can be connecting an infusion pump to a patient
at an infusion site. The infusion pump can have an integrated power
source 110 that is operably couplable to the optical element 102 of the
tubing itself. Another installation can be connecting a feeding device to
a patient at a feeding site where the tubing itself contains the power
source 110, not the feeding device. Upon correct installation, the tubing
set can illuminate or flash a known pattern or sequence to indicate
correct installation.

[0068] At 1004, operating parameters are set. The color of tube,
illumination intensity, and alarm limits for the various coupled sensors,
and other operating parameters are programmed into microcontroller 108
via device interface 112. In some embodiments, the operating parameters
are set automatically upon installation of the tubing set. For example,
because of the standardization of colors and patterns in the medical
industry, any tubing set connected to a specific device requiring a
standard color or pattern can automatically be programmed by the device
via device interface 112 to set microcontroller 108 with the standardized
illumination, standard limits, and standard intensity for the
application, without any additional human intervention. If the medical
professional desires a different color scheme limits, or intensity,
device interface 112, which can reside on a medical device, or as a
separate interface, can be utilized to program microcontroller 108.

[0069] At 1006, an initial set of tubing characteristics are sensed. If
pressure sensor 106 is present in the tubing set embodiment, as depicted
in FIG. 2, the pressure of the tube is sensed. Further, or alternatively,
any additional sensors, as described above, are activated to capture
their respective sensor indications. At 1008, a check of operating limits
is conducted. The decision point at 1008 is utilized to ensure that
operation of the tube is within the set limits. This type of limit or
boundary check is conducted for all attached sensors, or if, desired,
fewer than all attached sensors. If, for example, the pressure sensed by
pressure sensor 106 is inside of expected limits, normal operation
results at 1010. Normal operation 1010 can include a solid illumination
at the desired programmed light intensity, or no illumination, if
desired. If, however, the pressure sensed by pressure sensor 106 is
outside of expected limits, alert operation results at 1012. Alert
operation 1012 can include a flashing or patterned illumination to
indicate some sort of problem with the tubing set. For example, a quicker
flash might indicate a pressure or occlusion problem, whereas a slower
flash might indicate a temperature problem. In another example, a pattern
of three quick flashes followed by a pause of no illumination might
indicate an improperly connected tubing set. In yet another example, a
short flash followed by a long flash might indicate a microcontroller 108
fault. Any number of flashing or patterned flashes can be implemented to
indicate status. Further, any attached medical device can utilize the
illumination capability of the tubing set to indicate status for the
medical device by operation via device interface 112.

[0070] In either the case of normal operation 1010 or alert operation
1012, power source 110 interfaces with optical element 102 to illuminate
optical element 102 and the tubing set. When the tubing set is in normal
operation, the recursive loop from normal operation at 1010 back to sense
tubing characteristics at 1006 can be conducted in real time, or upon
expiration of a standard or programmed wait period. Further, in
operation, any of the operating parameters can be adjusted while the
tubing set is in use.

[0071] With reference now to FIG. 11, a system for medical tubing
detection and management 1100 could include an infusion manifold housing
1110 having at least one fluid channel 1120 therethrough. At least one
fluid input port 1130 could be provided in infusion manifold housing
1110. Each input port 1130 could be configured to connect fluidically to
illuminated medical tubing IT, respectively, and be in fluidic
communication with fluid channel 1120 through infusion manifold housing
1110. As used throughout this document, the term "illuminated medical
tubing" includes any suitable illuminated or otherwise optically
identifiable medical tubing or lines used with, e.g., infusion pumps,
substance delivery systems, and substance removal systems, such as those
described by example or otherwise contemplated herein. A fluid output
port 1140 could be provided in infusion manifold housing 1110, and be
configured to be in fluidic communication with fluid channel 1120 through
infusion manifold housing 1110. Fluid output port 1140 could also be
configured to connect fluidically to fluid output tubing OT. As used
throughout this document, the phrases "connect fluidically" and "fluidic
communication" are intended to refer to connections, and conduits or
means of transmission, that satisfactorily facilitate movement of fluid
through or between intended paths and locations. At least one photosensor
1150 could be provided in infusion manifold housing 1110. As used
throughout this document, the term "photosensor" includes any suitable
devices that are capable of sensing or detecting light or other
electromagnetic energy such as, e.g., optical sensors and photodetectors.
Each photosensor 1150 could be configured to receive light from the
illuminated medical tubing IT that is connected, respectively, to each
fluid input port 1130 (that is, in turn, associated respectively with
each photosensor 1150). Each photosensor 1150 could generate an output
signal (not depicted in the drawing) in response to light received from
the illuminated medical tubing IT. Such output signal could be, for
example, transmitted to a computer or other display means by any suitable
signal processing or transmission techniques (e.g., wireless transmitters
and receivers) for organizing infusion sets or drug compatibility
verification as will be described. It is to be appreciated and understood
that at least one infusion pump (not depicted) could be fluidically
connected to the illuminated medical tubing IT. In such an application of
system 1100, each infusion pump could be configured to generate a light
output (not depicted) that would be conducted from the illuminated
medical tubing IT associated with that pump to each respective
photosensor 1150 in housing 1110. The light output from each infusion
pump could be indicative of at least one characteristic of the pump, as
will be described below.

[0072] Referring now to FIG. 12, a system for medical tubing detection and
management 1200 could include an infusion manifold housing 1210 having at
least one fluid channel 1220 therethrough. At least one fluid input port
1230 could be provided in infusion manifold housing 1210. Each input port
1230 could be configured to connect fluidically to illuminated medical
tubing IT, respectively, and be in fluidic communication with fluid
channel 1220 through infusion manifold housing 1210. A fluid output port
1240 could be provided in infusion manifold housing 1210, and be
configured to be in fluidic communication with fluid channel 1220 through
infusion manifold housing 1210. Fluid output port 1240 could also be
configured to connect fluidically to fluid output tubing OT. At least one
light pipe 1260 could be provided in infusion manifold housing 1210. As
used throughout this document, the term "light pipe" is intended to
include any suitable means or devices for conducting or transmitting
light through, or between, intended paths and locations. Each light pipe
1260 could have a first end 1262 and a second end 1264; and the first end
1262 could be optically connected to each fluid input port 1230,
respectively. As used throughout this document, the term "optically
connected" is intended to refer to connections, and conduits or means of
transmission, that satisfactorily facilitate transmission of light
through or between intended paths and locations. At least one lens 1270
could be included in infusion manifold housing 1210. Each lens 1270 could
be optically connected to second end 1264 of each light pipe 1260,
respectively, and be configured to transmit light from each light pipe
1260, respectively, outwardly from infusion manifold housing 1210. At
least one photosensor 1250 could be provided externally from infusion
manifold housing 1210. In this regard, it is to be appreciated and
understood that manifold housing 1210 and its associated, aforedescribed
components could be deemed to be disposable--or for a single use or for
use with a single patient--while each of the potentially more expensive
photosensors 1250 could be reused since they are remote and separate from
disposable housing 1210. Thus in one embodiment, although not
illustrated, photosensors 1250 could be contained within a sensor housing
as part of a pump racking device or be provided on, e.g., an intravenous
apparatus or bedside utility pole. Irrespective of a particular
embodiment, generally each photosensor 1250 could be configured to
receive light from each lens 1270 and the illuminated medical tubing IT
that is connected, respectively, to each fluid input port 1230 (that is,
in turn, associated respectively with each light pipe 1260). Each
photosensor 1250 could generate an output signal (not depicted in the
drawing) in response to light received from the illuminated medical
tubing IT. Such output signal could be, for example, transmitted to a
computer or other display means by any suitable signal processing or
transmission techniques (e.g., wireless transmitters and receivers) for
organizing infusion sets or drug compatibility verification as will be
described. It is to be appreciated and understood that at least one
infusion pump (not depicted) could be fluidically connected to the
illuminated medical tubing IT. In such an application of system 1200,
each infusion pump could be configured to generate a light output (not
depicted) that would be conducted from the illuminated medical tubing IT
associated with that pump to each respective photosensor 1250 located
externally from housing 1210. The light output from each infusion pump
could be indicative of at least one characteristic of the pump, as is
next described below.

[0073] Referring to both FIGS. 11 and 12, it is to be appreciated and
understood that the output signal from each photosensor 1150 or 1250,
that could be transmitted to a computer or other display means as
aforementioned, could provide a relatively easy and efficient way of
organizing infusion sets and providing drug compatibility verification to
medical practitioners utilizing system 1100 or 1200. In particular, light
output from infusion pumps being received by sensors 1150 or 1250 could
be indicative of at least one characteristic of each pump such as, e.g.,
an identification of a drug being delivered to a patient or a "route of
infusion" to the patient. For example, a particular system 1100 or 1200
could be designated as "Epidural Only"; and if a pump for an intravenous
drug was erroneously connected to that system 1100 or 1200, then an alarm
signal could be generated from each sensor 1150 or 1250 before such
incompatible or adverse drug is delivered to the patient.

[0074] An example of a method of medical tubing detection and management
could include a step of providing a system for medical tubing detection
and management such as, e.g., shown in FIG. 11. The system could include
an infusion manifold housing having at least one fluid channel
therethrough. At least one fluid input port could be in the infusion
manifold housing, and be configured to connect fluidically to illuminated
medical tubing and be in fluidic communication with each fluid channel in
the infusion manifold housing. A fluid output port could be in the
infusion manifold housing and be configured to be in fluidic
communication with each fluid channel in the infusion manifold housing,
and to connect fluidically to fluid output tubing. At least one
photosensor could be in the infusion manifold housing. Each photosensor
could be configured to receive light from the illuminated medical tubing
that is connected to each fluid input port and generate an output signal
in response thereto. This example of a method could also include a step
of fluidically connecting at least one infusion pump to the illuminated
medical tubing. Each infusion pump could be configured to generate a
light output that is conducted from the illuminated medical tubing to
each respective photosensor in the infusion manifold housing. The light
output from each infusion pump could be indicative of at least one
characteristic of each pump; and each pump characteristic could include,
e.g., an identification of a drug being delivered to a patient from the
fluid output tubing.

[0075] Another example of a method of medical tubing detection and
management could include a step of providing a system for medical tubing
detection and management such as, e.g., shown in FIG. 12. The system
could include an infusion manifold housing having at least one fluid
channel therethrough. At least one fluid input port could be in the
infusion manifold housing, and be configured to connect fluidically to
illuminated medical tubing and be in fluidic communication with each
fluid channel in the infusion manifold housing. A fluid output port could
be in the infusion manifold housing and be configured to be in fluidic
communication with each fluid channel in the infusion manifold housing,
and to connect fluidically to fluid output tubing. At least one light
pipe, having a first end and a second end, could be in the infusion
manifold housing. A first end of each light pipe could be optically
connected to each fluid input port, respectively. At least one lens could
also be in the infusion manifold housing. Each lens could be optically
connected to the second end of each light pipe, respectively, and be
configured to transmit light from each light pipe, respectively,
outwardly from the infusion manifold housing. At least one photosensor
could be located externally from the infusion manifold housing. Each
photosensor could be configured to receive light from each lens,
respectively, and generate an output signal in response thereto. This
example of a method could also include a step of fluidically connecting
at least one infusion pump to the illuminated medical tubing. Each
infusion pump could be configured to generate a light output that is
conducted from the illuminated medical tubing to each respective
photosensor located externally from the infusion manifold housing, via
the respective light pipes and lenses. The light output from each
infusion pump could be indicative of at least one characteristic of each
pump; and each pump characteristic could include, e.g., an identification
of a drug being delivered to a patient from the fluid output tubing.

[0076] Irrespective of a particular embodiment, it is to be appreciated
and understood that systems for, and methods of, medical tubing detection
and management--as described by example or otherwise contemplated
herein--may be generally characterised in that the systems and methods
could be configured to identify each of a plurality of infusion pumps
that are connected, by illuminated medical tubing, respectively, to each
fluid input port in the infusion manifold housing. It is also to be
appreciated and understood that the systems and methods may thus further
facilitate the organization and communication of visual indications of
characteristics relating to the types and operating statuses of the
illuminated medical tubing as described herein or as disclosed in the
aforecited co-pending application Ser. No. 13/296,883.

[0077] Although not particularly illustrated in FIG. 11 or 12, it is to be
appreciated and understood that aforedescribed embodiments of illuminated
medical tubing (such as, e.g., various embodiments of single and dual
lumen tubing as described herein) may be used individually or in various
combinations with systems for, and methods of, medical tubing detection
and management, as described or otherwise contemplated herein.

[0078] Further, although not illustrated, it is to be appreciated and
understood that systems for, and methods of, medical tubing detection and
management, as described or otherwise contemplated herein, could include
any of the usual attributes of an infusion set manifold such as, e.g.,
fittings, seals, luer locks, and stopcocks, etc. Also, it is to be
appreciated and understood that systems for, and methods of, medical
tubing detection and management, as described or otherwise contemplated
herein, could also include any desired sensors to monitor characteristics
of the tubing, fluid, or surrounding environment (e.g., the
aforementioned pressure sensors, occlusion sensors, fluid flow sensors,
temperature sensors, liquid density sensors, air bubble sensors, salinity
sensors, pH sensors, dissolved oxygen sensors, conductivity sensors, and
electrolyte sensors) whether individually or in any desired combinations.

[0079] Although illustrated in FIGS. 11 and 12 as embodiments with four
tubing inputs, it is to be appreciated and understood that systems for,
and methods of, medical tubing detection and management, as described or
otherwise contemplated herein, could include any desired number of tubing
inputs provided that such systems and methods satisfactorily function as
aforedescribed. Analogously, any number of systems for medical tubing
detection and management could be employed in a particular care setting,
as may be desired for, e.g., maintaining readily identifiable
organization of a relatively large number of infusion lines that each
could be distinctly and extremely important in treatment of a critically
ill patient.

[0080] Additionally, it is to be appreciated and understood that tubing
outputs of systems for, and methods of, medical tubing detection and
management, as described or otherwise contemplated herein, could also be
visually identifiable by, e.g., any of the aforedescribed illumination or
color scheme techniques of illuminated medical tubing, as may be desired
in a particular care setting.
